Bio-Rad Extends Range of Anti-Idiotypic Antibodies for Use in Preclinical & Clinical Drug Development
Bio-Rad Laboratories, Inc. recently extended its range of recombinant monoclonal anti-idiotypic antibodies with the introduction of six antibodies specific to dupilumab (Dupixent) and the addition of new evolocumab (Repatha), ipilimumab (Yervoy), and secukinumab (Cosentyx) antibodies. These ready-made antibodies are suitable for developing selective and sensitive pharmacokinetic (PK) and anti-drug antibody (ADA) assays for dupilumab, evolocumab, ipilimumab, and secukinumab, and their biosimilars.
Dupilumab limits inflammatory immune responses by targeting IL-4Ra and is approved for treatment of severe atopic eczema. Bio-Rad’s six new anti-dupilumab antibodies can be used to develop PK bridging ELISAs to measure free and total drug, or as a surrogate positive control or reference standard in ADA assays. The range includes two fully human IgG1 clones and four TrailBlazer™ Antibodies with a SpyTag incorporated into their heavy chain, enabling site-directed conjugation or fast switching to a bivalent Fab or a full-length Ig-like format within an hour.
Bio-Rad has also expanded its anti-ipilimumab and anti-secukinumab portfolio to become the first provider of antibodies specific to the drug-target complex, allowing the detection of bound drug. HRP-labeled TrailBlazer antibodies are also now available for evolocumab.
“Bio-Rad’s leading portfolio of monoclonal anti-idiotypic antibodies offers researchers greater flexibility for the development of highly selective and highly sensitive bioanalytical assays,” said Dr. John Cardone, Marketing Manager, Custom Antibodies, Life Science Group, Bio-Rad. “Our drug-target complex binders are unique to Bio-Rad, enabling researchers to detect drugs in the target-bound state, and all our anti-idiotypic antibodies are provided with in-depth data packages for reproducible results.”
These new anti-idiotypic antibodies are approved for in vitro research, for commercial in vitro testing services to support preclinical and clinical drug and biosimilar development, and patient monitoring.
